1. I put one in a folder devoted to THAT horse, with the newest one on top. That way each horse has a progressive history to show where they are at any given time. When the horse sells, their file goes with them.
2. I have a binder that has dividers with every judges name I have a sheet for. The second copy gets filed under that judges name, newest on top. You see, every judge has their likes and dislikes. They have real preferences in what they want out of a horse. The tests are a look into what they deem most important.
When I go to a show, I look up and see who the advertised judges are. I pull out the binder and look at what I need to really focus on. When I get to the show, I find out which judge is on the rings I will be riding and make subtle adjustments to my riding. It really helps!!
Those old tests score sheets are one of the best training tools you have.
